This Chinese-language tutorial, uploaded on August 14, 2025, explains RTranslator setup and translation on Android. The speaker describes it as free and open source, with offline operation after the initial downloads. He associates broader language support with versions after 2.1 but does not identify the exact release installed.
The walkthrough starts with downloading an APK from the project's releases page. According to the setup explanation, Whisper converts speech to text and Meta's NLLB translates between languages. The speaker cites roughly 6GB of phone RAM and an initial model download of about 1.24GB. He also warns that downloads may be slow without a VPN in his context; the speaker describes later inference as offline, but does not demonstrate a network-disconnection test.
Speech output uses the phone's TTS engine. The tutorial shows Google TTS settings, voice-data downloads, and controls for speech speed and pitch. The speaker describes over 30 main languages, with roughly 100 available when additional languages are enabled through settings labeled for lower-quality language and TTS support.
The demonstrations cover text translation and a single-phone walkie-talkie mode, including a Chinese-English restaurant exchange. Users can disable spoken output and show the translated text instead. The speaker also explains a two-phone conversation mode that requires RTranslator on both devices, but does not demonstrate it. These setup details describe the dated walkthrough rather than establish current requirements or translation accuracy.
